I remember a staking operation where we used linear motors for positioning.
They should easily achieve the speed you need. I searched a bit for a short

Compumotor was the vendor for this project, IIRC. They would be a good
choice for an industrial automation application. If you're adventurous, I've
seen compumotor stuff go for a tiny fraction of new on eBay.
